sv claims. (ci. zi-zos) This invention relates to slide fasteners such as commonly used in lieu of buttons to detachably unite the edges of openings ingarments such as shirts, sweaters, drawers, shoes, etc., as well as i'n articles like tobacco pouches, hand bag's, etc.

In slide fasteners asordinarily made,.the invterengaging slide-operated metallic lugs on the two attaching tapes are exposed both at the back I. and at the front. Thus when the fasteners are used on undershirts, and sweaters for example. the metal is apt to come in contact with the skin of the wearer, and in closing the fasteners the hair of the skin is often caught between the lugs, thereby causing and discomfort.

Again, with the slide fasteners on shoes, the unprotected lu'gs are likely to pinch and tear the stockings incident to operation of the fasteners.

In still other instances as for example, tobacco pouches, particles of become lodged between the lugs of the fasteners and interfere .with -the slides.

considered from the broadest my mvention is` directed toward obviating the above.

Pig. XI is a fragmentary perspective view of one of the edge tap of the modified slide fastener shown in Fig. X.

The form of my improved slide fastener delineated in Figs. I-IV comprises a pair of attaching fabric tapes l and 2 vwhich'are identical in construction and adapted to be sewed or otherwise secured along opposite edges of an opening in articles like sweaters, shirts, shoes, hand bags. tobacco pouches, etc. Each tape I. 2, it will be affords a central tongue l with an incorporated ^-cord l providing a thickened edge or bead 0. At opposite sides each tape I is moreover formed with flanking plain wings 1 and I respectively, said wings merging into the body portionl at about the longitudinal median of the latter and observed, has a main or bodyportion t which extending somewhat beyond the bead t of the tonguelasshowninFigJV'. 'Iiietapes I and:

I preferably produce with the wings 'l and 8 inte# v gral on a suitable narrow fabric loom, although if desired or found convenient in practice, the wings 1, l may be separately woven and afterwards sewed to the body portions 3.

In making up the fastener, thev interlocking metallic lugs I, which may be of any of the common conventional types, are clinched at uniformlyspad intervals over the beaded edges 0 of thetongulasshowninrigalandninacccrdance with the practice ordinarily followed in 'the art. In the assembled fastener, it will be that the nanking wings 1 and I of the i and 2 overlap and completely conceal the As a result, not only is the fastener given more finished and attractive appearance, but lugs i are prevented from contacting directe 'iii with the fastener. From Fig. I! it is to be particularly observed, that the wings 8 of the tapes l and 2 also ove'rlap the anterior portion Ill of the slide member Il of the fastener; while at the front, the posterior portion I2 of said slide member overlies the wings 1. Thelatter feature is also clearly shown in Fig. I.

with the skin of the person wearing a garment y The texture of the tape mayfbe as shownin Figs. VI and VlI, 'wherein the wams orlengthwise running threads of the body portion I are indicated at andthe warns of the wings 1 and 5 l at i5 and i4 respectively. A single weft thread is employed in the weaving, these threads being indicatedy at il. From Fig. VI it will be observed that theweft Ilpassesacrossthefuli width' of the body Aportion of the tape, around the bead cord 5,' and then back again, being incidentally interlaced with the varias il. This pick cycle is graphically indicated by the snowed line in Fig.

VDI. In the next pick cycle, the weft il passes from left to right the full width of the 'tape as shown in Fig. VII and graphically indif cated by the arr-owed line in Fig. IX, around the l bead cord 5, then leftward to the juncture I1 between the tongue I and the wings l and 8,

then rightward of the wing l around the freer.

`edge of the latter andleftward of the saine, then rightwad'of'the wing 1 around the free edge of the latter and back to the juncture Il, and finally from thence to the rear edge of the body portion, the weft being interlaced 'during the last A '25;desenbed cycle with the warps n, u and |s.

Thesetwo cycles are continuously repeated as the weaving progresses, with the result there 'are just twice as many layers of the weft Ii in `the body portion 3 as there are in-'the wings 1 30,and l with incidentfonnation of open inper- 'forate suturesf such as .shown diagrammatically at I8 in FigrV at the junctures of said wings with the portion ,of the tape. These open or V perforate junctures Il compensate automatically rar @mei-ennui shringgge between the wings 1 and '8 and the body portion I ofthe tapeduring washor dyeing opeations, with avoidance of buckling or distortion such as might interfereA with proper operation of the completed slide fastener,-

40 or which would detract' fromthe appearance of the fastener. Preferably, in' weaving the tape, I employ a silk or rayon-weft t! throughout. silk -or rayon warps I4 in thewingsl and 8, and warps I3 of cotton'or otherr relatively inexpensive yarn 45 in the body. portion 3 of the tape since said body portion isf'hidden bythe material of the article on which the slide fastener isf-used. The diversed yarns may give rise. tothe differential shrinkage which has been mentioned, but this 50 will be automatically compensatedgfor by the .o pen or perforate junctures Il asexplained. The above method of forming the tape is to be regarded as an example of many other ways in which the tape can be made in practice, the para- 55 mount consideration being that the wings 1 and 8 are integrally formed with the body portion 3 of the tape. f

In the modified form of fastener illustrated in` Figs. X and n the tape la is formed with but a 60 single flanking wing 1ae- `The tape 2a, on the pther'hand, isnke thetapes l and z of Figa 1 and II, i. e., formed with two'ilanking wings la and la, the wing abing howeverlof a greater width so as to 'overreach the lugs 9a on both tapes as shown in Fig. Xi The modified tapes la and 2a'. may be woven in a manner similar to that described of the tapes I and 2 of` Figs. I-IV. f 5

Having thus described my invention, I claim:

l. A slide fastener comprising a pair of attachingY tapes each with a central tongue having a bead over which the metallic lugs of the fastener are'secured, and ilanking wings at opposite sides 10 Aextending beyond the beaded edge of the central tongue to cover the lugs at the front and the back of the fastener; and a metallic slide to cooperate-with the lugs on the two tapes to open "and close the fastener, the anterior portion of l5 fthe slide overlying the cover wings of the tapes at the front of the fastener, and the posterior A portion ofthe slide being overlapped by the cover wings at the back of the fastener. Y

2. A tape for slide fasteners integrally formed 20 with a central tongue having an edge bead for :anchorage of the metallic lugs of the fastener, and flanking plain cover wings for the lugs extending to different extents beyond the beaded edge of the tongue respectivelyl at opposite sides 25 of the tape.

and with ilanking plain cover wings for the lugs extending 'to diiferentextents beyond the beadedfli edge of the tongue respectively at opposite sides of the tape.

`5. In a. slide fastener wherein a slide cooperates with two sets of serially-arranged interlocking lugs, attachment tapes to which the lugs of the ,respective series are secured, said tapes having integrally-formed plain wings merging longitudinally into the body portion and jointly providing overlaps to cover the lugs at the front and the Y back of the fastener as well as the posterior' por- 5 0L tion of the slide.

6. In a. slide fastener wherein a metallic slide cooperates with two sets of serially arranged lugs; tapes to which the lugs of the respective series are secured, said tapes having complemental= plain edge wings overtravelled by the anterior portion of the slide and? covering theflugs 'at the front of the fastener, androne of said tapes having a wing for covering the lugs as well as the pos- A 'terior portion of the slide atthe back the 60 fastener.
